A fair die is tossed twice in succession. If $$\mathrm{X}$$ denotes the number of fours in two tosses, then the probability distribution of $$\mathrm{X}$$ is given by

$$\mathrm{X}=x_i$$	0	1	2
$$\mathrm{P_i}$$	$$\frac{1}{36}$$	$$\frac{25}{36}$$	$$\frac{5}{18}$$

$$\mathrm{X}=x_i$$	0	1	2
$$\mathrm{P_i}$$	$$\frac{25}{36}$$	$$\frac{1}{36}$$	$$\frac{5}{18}$$

$$\mathrm{X}=x_i$$	0	1	2
$$\mathrm{P_i}$$	$$\frac{25}{36}$$	$$\frac{5}{18}$$	$$\frac{1}{36}$$

$$\mathrm{X}=x_i$$	0	1	2
$$\mathrm{P_i}$$	$$\frac{5}{18}$$	$$\frac{1}{36}$$	$$\frac{25}{36}$$
